University of California, Los Angeles, CA Jet Propulsion Laboratory, Pasadena, CA 3 Texas Instruments, Dallas, TX 2 Terahertz image and spectroscopic systems (operating in frequency range from 300GHz to 3THz) have drawn increasing attention recently due to their unique capabilities in detecting and possibly analyzing concealed objects. The generation of terahertz signals is nonetheless nontrivial and traditionally accomplished by using either free-electron radiation, optical lasers, Gunn diodes or fundamental oscillation by using III-V-based HBT/HEMT technology [13]. These prior techniques suffered major disadvantages of size, cost, complexity and sometimes even the need of cryogenic cooling
